To all whom it may concern Be it known that I, CHRISTOPHER F. STAR-LIPER, a citizen of the United States, residing at Hampton, in thecounty of Carter and State of Tennessee, have invented certain new anduseful Improvementsin Shaft- Collars, of which the following is aspecification, reference being had to the accompanying drawing.

, This invention relates to an improved shaft collar and has for itsprimary object to provide a sectional stop collar for shafts which maybe very easily, quickly and securely applied to the shaft.

The invention has for a further object to provide a collar having twocomplementary sections, the ends of which are formed for interlockingengagement and are adapted to draw the collar sections into frictionalbinding engagement with the periphery of the shaft. v

' The invention has for a further general object to provide a collar ofthe above character which is simple in its construction, strong, durableand serviceable in practical use and capable of manufacture at acomparatively small cost.

With the above and other objects in view as will become apparent as thedescription proceeds, the invention consists'in certain constructions,combinations and arrangements of the parts that I shall hereinafterfully describe and claim. I For a full understanding of the invention,reference is to be had to the following de-. scription and accompanyingdrawing, in which i Figure 1 is a sideelevation of my improved collarshowing the two sections thereof interlocked; Fig. 2 is an edge view ofthe collar applied to the shaft; and Fig. i

3 is a detailperspective view of one of the collar sections.

Referring in detail to the drawing, 5 designates the collar sectionswhich are identical in construction and are preferably formed of steelor other suitable metaL- One end of eachcollar section is provided witha relatively narrow extension -6 projecting circumferentially from theinner edge thereof. Upon the outer face of this extension at itsextremity the dove-tail locking tongue 7 is formed. -The inner inclinededge of this tongue in conjunctionwith the opposed end edge of thecollar section outwardly of the extension 6 produces a recess '8. Theend edges of the collar and its extension 6 as well as of the tongue 7are beveled, as clearly shown in Figs. 2 and 3 of the drawing. Theopposite end of each collar section is also provided with a narrowcircumferential extension 9 at its outer edge, upon the extremity ofwhich the inwardly projecting lug 10 is formed. The inner edge of thistongue is inclined, as at 11, and in conjunction with the reverselyinclined end face 12 of the collar and the extension 9 forms the recess13 which is designed to receive the dove-tail locking tongue of theother collar section. The end edges of the extension 9, lug 10 and thecollar section 5 are beveled in a similar manner to the faces on theopposite, end of the collar section so that when the collar sections areconnected in the manner to be later described, the beveled end faces ofone section will properly engage the beveled faces of the other section.

I The diameter of the bore or opening formed by the two collar sectionswhen they are completely assembled, is slightly less thanthe diameter ofthe shaft to which the collar is to be applied. In applying the collar,one of the sections 5-is arranged upon the shaftindicated at S in Fig.2, and the other section then moved longitudinally of the shaft and thetongue 7 and lug 10 thereof engaged in the sockets or recesses in theends of the first named section which are designed to receive the same.As the beveled end faces of one collar section ride upon the.correspondingly beveled. faces of the other section, the two collarsections are drawn together into frictional clamping engagement upon theperiphery of the shaft. When first applied, one of the collar sectionswill project a slight distance beyond the face of the other collarsection, as clearly indicated in Fig. 2 of the drawing. As the innerwalls of the collar sections become worn, said sections are driven moretightly together so as to compensate for such Wear until the twosections are disposed in the same plane about the shaft to which theyare applied.

From the foregoing description, taken in connection with theaccompanying drawing, the construction, manner of operation and severaladvantages of my invention will be clearly andfully understood. Myimproved sectional collar may be very easily and quickly tight clampingengagement upon the shaft so that supplemental holding means for thecollar may be dispensed with. My invention may also be manufactured at asmall cost and is extremely durable as well as highly serviceable andconvenient in practical use.

I claim:

1..A shaft collar including two complementary sections, each sectionbeing formed at its ends with a radially extending dovetail projectionand a radially extending dove-tail recess inward of the projection,

said recesses and projections on one section interlocking and matingwith the projections and recesses on the other section.

2. A shaft collar including two comple- 'mentary sections, each sectionbeing formed at its ends With a radially extending dovetail projectionand a radially extending dove tail recess inward of the projection, saidrecesses and pro ectlon on one sectlon interlocking and mating with theprojection and recesses on the other section, the under faces of saidprojections and recesses being laterallyinclined in the same direction.

3. A shaft collar including two like arouate sections, each sectionhaving on its inner edge at one end a dove-tail recess defining one edgeof a beveled faced inwardly extending radially disposed lug and havingon its outer edge a recess defining one edge of a dove-tail outwardlyprojecting radial tongue, the tongue and lug of one section interlockingwith the tongue and lug of the other section.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
